Kolbe awning windows are energy efficient and provide excellent ventilation. Bottom venting allows them to be slightly open even in light rain. They close and seal tightly to the frame and weather-stripping. Many models, shapes and configurations are available. Awnings are often stacked and mulled for a wall of windows that invites passive solar heat in while allowing fresh air when needed. Operation types include crank-out and push-out. To take energy efficiency to a new level, triple-pane glass is available for many of our awnings.
